MATLAB Basics: Cell arrays for holding different data types

Sometimes in MATLAB you are going to want to store different data types together in one construct rather than try and keep track of different variables. Structures work for this, but sometimes it is nice to be able to refer to the data in row and column notation rather than by field name. That is where cell arrays work best.

This video will show the construction of a cell array that contains four scalars and then a string is added. Finally, a cell array is put inside of the original cell array. This is possible, because cell arrays can hold any data type.

    Thanks a bunch for this easy-to-understand video. This short post taught me a lot!! I was going to so many forums to learn this thing, but this is where I finally understood it clearly. Thanks again. :)

Wrap code fragments inside <pre> tags, like this:

<pre class="code">
a = magic(3);
sum(a)
</pre>

If you have a "<" character in your code, either follow it with a space or replace it with "&lt;" (including the semicolon).
